Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518262, here are decompositions:

13 + 518249 = 518262
23 + 518239 = 518262
29 + 518233 = 518262
53 + 518209 = 518262
71 + 518191 = 518262
83 + 518179 = 518262
103 + 518159 = 518262
109 + 518153 = 518262

Showing the first eight; more decompositions exist.
